ST-40, The Pipeline Replacement Machine

This is a mini-unit, with the pulling capacity of 40 tons, applying the trenchless technology for replacement of average-diameter pipelines.The main purpose of this innovative device is trenchless replacement of cast iron, ductile iron, concrete, ceramic and other pipes by means of static pipe bursting. It is possible to keep the same diameter as the old pipe or to increase it by some amount, depending on the soil conditions.
One of the advantages of ST-40 is its compact size, allowing it to be operated in extremely confined spaces, such as Ø1000 mm wells.
High degree of automation reduces the crew number and increases the safety level at the construction site: in particular, the presence of personnel inside the well is not required during the pipe-bursting process.

Application:

The trenchless procedure for replacement of pipelines having the diameter up to 315 mm, up to 120 m long.

Features

Automated rod-feeding and automated pulling of the bursting head

Innovative system of rods with pivot joints

Ergonomic back-pushing device for short pipe modules

High safety

Small size and weight
